A grateful look crosses Bruce's face at the answers he gets, looking assured by it and just... glad. Glad that in spite of it all he had Tony and Pepper, could have a bit of his life with them and that at the very end, he could see the both of them again.
He starts to cough once more, this one much worse than any of the ones he had before. His time was coming, and soon. He could feel himself weakening by the second. He didn't have much time left now.
All his life he had been waiting for the moment where he could finally die, but yet right here, right now... he didn't want to die. He wanted to live, and spend his days with Tony and Pepper here, together. But he supposes that is how life has always been - unfair, even to the very end.
